Craig, you'll notice the distance from the front wheel to the front A-pillar is about the same on all of those.

As is the angle of the B Pillar just behind the rear window.

It has to do with crash structure, when the front left or right take a partial block hit there needs to be a certain path/give to get a high rating.

There are many constraints that are tying the cars together in their dimensions and angles.

I like that Corvette met the new rules when they made the C7 by making something new instead of trying to stretch something old. The C7 is a better looking car than any of the three you linked.

Personally I'm just glad I am not responsible for trying to style the 911 in a modern environment.
